Fynny: Building a one-stop debt relief app with 30% better task success

Designed mobile-first growth, acquisition, and activation flows in Figma, improving onboarding completion and reducing repayment setup time. Streamlined fragmented debt management into one go-to platform, boosting task success to drive growth in monthly repayment volume.

Timeline

September 2024 to January 2025

Industry

Finance B2C

Typology of Project

Mobile UI and Research

Team

Client CEO, Dev Team, 4 UX Designers, NL Government Stakeholders

Tools

Figma, Optimal Workshop, Hotjar, Maze, Miro

My Role

As one of the 4 first Product Design consultants of the start-up, I led the end-to-end process of user research, defining interaction flows, crafting visual design, building prototypes, and conducting usability testing to deliver a streamlined and user-centered product experience.

Role Specifics

Built the information architecture and co-created core user flows
Led generative + formative research
Conducted interviews with youth, social workers, and municipality debt experts
Launched the initial design system
Facilitated MVP planning with client and development teams
Tested usability with card sorting, A/B testing, and task success tracking

Outcomes

The Challenge

"I receive so many letters with different debt deadlines from various agencies. I don’t know what I owe, who I owe it to, or when I need to pay them."

• Young adults in the Netherlands—especially those aged 18–35—struggle to manage debt caused by unpaid health insurance premiums.
• They receive communications across disconnected channels (letters, emails, agencies), making it hard to understand what’s owed, when to pay, or who to pay.
• Many feel ashamed to seek help, and lack tools that speak to their diverse financial behaviors.

Stakeholder Concerns & Key business objectives

Improve repayment outcomes for debt collection partners

Increase sponsor engagement through demonstrable user benefit

Ensure long-term product scalability and legal feasibility

We needed to design a product that would serve users’ mental models while aligning with business models rooted in public service and funding support.

The Solution

I co-designed Fynny as the first mobile app to unify fragmented debt communications, enable personalized debt management, and guide users through actionable financial steps.

It features:

A personalized onboarding quiz to tailor content to user behavior
A central dashboard for debt progress and payment timelines
Interactive budgeting and simulation tools
Bite-sized gamified financial microlearning and helpful daily tips
Gamification and strategic Reward incentives for Financial Confidence

Impact created

30% improvement in usability, measured through task success rates and reduced navigation friction
4+ MVPs conceptualized, designed, prioritized, and tested with real users and stakeholders
2.3M+ potential users identified through collaboration with government partners and debt organizations
Delivered a scalable system and validated user flows to support future AI-based personalization and feature growth

PROCESS:

Understanding the User problem areas

Product, Market & User Research

The project began with deep generative research to understand the debt challenges faced by Dutch youth and identify gaps in the current system. I conducted:

In-depth Interviews with 15+ young users, social workers, and municipal debt specialists
Contextual inquiries to observe behaviors around debt communication and planning
Desk research on national youth debt statistics and financial stigma
Ecosystem mapping to understand the roles of institutions, users, and intermediaries
A review of survey insights from 45,000+ youth collected by Flanderijn

Persona Insights

Research revealed 8 distinct financial personas among Dutch youth. We used these insights to design features and UI tailored to diverse behaviors—understanding that a Planner interacts with the app very differently than a Spender. This behavioral lens shaped our design decisions to ensure Fynny supports a wide range of financial mindsets and user needs.

The Spender
The Spender enjoys spending money and often prioritizes short-term gratification over long-term financial stability. They may struggle with impulse buying and frequently spend beyond their means, leading to debt or difficulty saving.

Interviews with the target audience, Municipality officials, Debt specialists and volunteer social workers revealed multiple missing system gaps and user pain points.

"I receive so many letters with different debt deadlines from various agencies. I don’t know what I owe, who I owe it to, or when I need to pay them."

"We have been seeing a trend of users using 'Buy Now Pay Later' excessively with less idea about how the debt keeps piling up along with insurance."

Information and Flow Audit

Our first step was to map the entire ecosystem of how users currently manage debt. We found:

No centralized system to track debts or deadlines
Overwhelming paperwork from multiple agencies
Stigma around seeking help, especially among youth
Fragmented user touchpoints across municipalities, banks, and agencies

This revealed core opportunity areas:
➡ Centralize debt info
➡ Reduce friction in financial setup
➡ Make debt management feel doable
➡ Need for gamified incentives for habit building

We conceptualized Fynny's potential features for strategic problem-solving.

The main question arose on how to concise the elaborate research insights, Fynny's goals, our design prioritizations to the user's benefits to strategize Fynny's feature library and its MVPs.

Product Architecture Map

Prioritization for MVPs

I performed card sorting sessions with users to understand what they expect on the app.

Insight 1
Users intuitively group financial tracking data with behavioral insights.

Card sorting Results Dendogram

Insight 2
Users expect actionable data and debt trackings on the home page itself.

Research analysis chart

Onboarding and set-up Flow:

I tried to design the work flow in a process that would seem most intuitive to the user and also take in all essential information for the user to develop the financial dashboard as they onboard the app for the first time.

Financial Management Journey Mappings

The intent of this flow is to guide users through actionable steps for effectively managing their debt while fostering healthy financial habits. By providing structured assistance and practical tools, the flow aims to empower users with the knowledge and resources needed to navigate their financial challenges. Additionally, it offers tailored financial tips to enhance users' financial literacy, enabling them to make informed decisions and achieve long-term stability.

Design Hypotheses

To balance complexity with clarity, I developed three design hypotheses:

1. Action builds confidence

Users who see small wins (e.g., visual debt progress) are more likely to stay engaged.

2. Context reduces friction

Presenting just the right data (budget, payments, tips) at the right time will prevent overload.

3. Gamification Fuels Engagement

Incorporating game-like elements, like badges, streaks, and milestones, alongside interactive micro-learning stories lead to rewarding, habit-forming journey.

Start of Design Explorations

Applying insights to low fidelity wireframes, we conceptualized the base visual for the app fatures.

Evaluative Research

Early Concern: Financial Data Overload? Finding the right balance.

I balanced concerns about overwhelming users with the need for realistic financial visibility. Two prototypes were tested to find the right approach.

Iteration 1:
65.3% mis-click rates
37.5% drop-off rates
0% direct* success rates

...were observed when essential features were not prominently displayed on main pages, causing users to struggle with navigation and fail to achieve their goals. Card-sorting results confirmed that these features needed to be placed in primary, highly visible areas of the app.

Data analysis from A/B Testing results

Iteration 2:

50% direct success rates

All main action-based financial data and tools need to be on the Home page, and intuitive cross-links must be provided.

Data analysis from A/B Testing results

Design Developments

Iterative design process and attaching research insights led to me understand user needs and include them in the final design stages.

Designing for Scalability and Implementation

In the later stages, I focused on preparing by addressing platform nuances, accessibility needs, and developer integration. These steps helped ensure the design was not only user-centered but also technically feasible, inclusive, and ready for smooth implementation.

Accessibility check-ins

Accessibility was built into the design system from the start, ensuring proper color contrast, readable font sizes, and touch target compliance.

Preparing for Developer hand-offs

I organized annotated Figma files with clear component naming, redlines, and usage guidelines to simplify hand-off. Regular collaboration with developers ensured alignment on interaction behaviors, responsive states, and edge case handling before the build phase began.

iOS and Android variations

We designed with platform-specific conventions in mind, ensuring a native feel for both iOS and Android users. Component sizing, navigational patterns, and interaction behaviors were tailored according to Human Interface Guidelines (HIG) and Material Design standards.

Core Design Features

Design solution strategies

We translated insights into 4 strategic pillars:

Making debt visible and manageable, support diverse behavioral archetypes.

Centralized dashboard for payments, deadlines, and agency info. Quick cards design style to get a cohesive overview.

Simplify complex financial decisions

Tools like simulation calculators, budget planners, and auto-prioritized to-do lists.

Foster confidence through micro-learning

Bite-sized, gamified content that makes financial literacy feel achievable.

Progressive onboarding to build early trust

Gradually introduces key tasks to reduce overwhelm and help users feel confident from the start.

Gamification and Strategic Incentives for Financial Confidence

To foster long-term financial habits and increase user retention, I designed a Badges and Rewards system that turns financial progress into a motivating journey.

This approach uses gamification to transform complex financial tasks into achievable milestones, reinforcing positive behavior through consistent, personalized rewards.

Users earn badges like "6-Month Streak" and "Payment Planner" for consistent, on-time payments, building financial discipline over time.

Behavioral Nudges:

Using motivational triggers like in-progress badges and streak tracking, users are encouraged to stay on top of their goals.
Personal streak counters and upcoming milestones drive repeat engagement.

Progressive Rewards for Consistency

Milestone-based achievements, like "Debt-Free Month" and "No Late Fees", reinforce good financial habits and reduce financial stress.

My key take-aways

Behavior-Aware UX Works

Recognizing different user mindsets—from avoidant to proactive—led to a more empathetic, supportive product experience.

Data + Empathy = Better Design

User interviews and card sorting balanced stakeholder assumptions with actual needs, leading to informed trade-offs.

Cross-Sector Collaboration is a Superpower

Designing with municipal governments taught me how to bridge policy, business, and user goals without losing clarity.
